What kind of advanced features? I understand some form of good 
firewalling is available, but do you know of any features related to 
bandwidth shaping, or QoS control on any of those routers? I'm trying to 
figure out if there is a dedicated device that handles QoS and shaping 
(I'd like to do that, but I doubt such a box is available for a 
reasonable price).
